MACHINE FOR SEWING HOOKS AND EYES ON CARDS.

SPECIFICATION forming part of Letters Patent No. 650,553, dated May #39, 1900.

Application filed May 31, 1898. Serial No. 682,154. (No model.)

To all whmn it may concern:

Be it known that I, TIMOTHY .T. CARMODY, a citizen of the United States, and a resident of Vaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Machines for Oarding Hooks and Eyes, of which the following is a full, clear, and exact description, whereby any one skilled in the art can make and use the same.

My invention relates to that class of machines for sewing hooks and eyes upon cards, and more particularly to the means and devices for holding the card and thread during the cutting operation, and also to the means by which the thread between the several cards is severed.

The object of my invention is to provide in a machine of this class means for holding and severing the thread and for securing the thread; and to this end my invention consists in the device as a whole, in the combination of parts, and in the details and their combination, as hereinafter described, and more particularly pointed out in'the claims.

Referring to the drawings, Figure l is a top or plan view of the table and parts mounted thereon, illustrating my invention, the sewing mechanism being removed. Fig. 2 is a view in front elevation of the same, showing the needle and needle-bar in relation thereto. Fig. 3 is a View in side elevation, looking from the left of the machine as shown in Fig 1, the sewing mechanism being removed. Fig. 4 is a detail perspective view of the cutter-box. Fig. 5 is a diagram view illustrating the mechanism with the cutter in its normal position. Fig. 6 is a detail diagram view illustrating the position of the parts with the cutter in position to sever a thread.

In order to enable hooks and eyes. to be attached to cards, as by means of a sewing-machine, a holder has been provided supporting connected hooks and eyes in proper position with relation to each other and also in a position having particular reference to the card on which they are to be sewed, the whole being fed along the sewing-machine and across the path of movement of the needles by means of ordinary known devices for such purposes. The hooks and eyes are sewed to a card in limited nu mbersethat is, in two or more rows, making up a dozen or other desired number of the hooks and eyes on each card. This operation requires a separation of the card or contemplates the use of separate cards, and

as the thread used in the sewing-machine is of a continuous length it must be out between the cards.

In prior devices of the class illustrated and described herein an objection has been found from the fact that at that edge of the card near which the last stitch is taken the thread is left more or less loose in the needle-hole, and if any pull is exerted on the loose end there is danger of unraveling the whole length of stitches, thus severing the hooks and eyes from the card. It is therefore desirable to fasten this last stitch in some way, and by. my improvement such means are provided. A further objection to prior devices of this class has resided in the fact that in severing the thread after the last stitch has been made the application of the cutter to the stitch pulls upon the thread to an extent to cause the unraveling hereinbefore referred to, and I have provided means herein for holding the thread in such manner during the cutting operation that this unraveling is prevented. My invention also provides means for holding the ends 80. of two cards so that they will not be carried upward by the cutter in the cutting operation.

I have also provided means whereby the cutter will operate quickly, so as not to interfere with the forward movement of the cards on which the hooks and eyes are being sewed.

In the accompanying drawings the letter a denotes the table of an ordinary sewing-ma chine, the mechanism for feeding the thread and for operating the needles being of any 0 usual and well-known type.

On the table a are secured supports 19, in which are mounted feed-shafts b, supporting feed-pinions b and driving-pinions b The driving-pinions are operatively connected by means of gears 5 located between the pin ions, one of the gears being operatively connected with a feed-ratchet c, operated by a pawl c, pivoted to an arm a secured to the ordinary feed'shaft a. of the machine.

In the operation of the device a holder d is provided with hooks and eyes (1 d held loops of the hooks and eyes and fastening them to the card.

A duplicate set of feed-pinions is illustrated herein and the hooks and eyes are'held on the holder by means of spring-fingers, which allow the card, with the hooks and eyes secured thereto,t0 be removed from the holder by the application of slight force.

The mechanism above described is of old and well-known construction and forms, except in combination with the parts to be hereinafter described, no part of the present invention.

On the stud 0 carrying the feed-ratchet c, is loosely mounted a cutting-ratchet 0 held against backward movement, as by means of a detent c. The ratchets c and project through the table a to an extent to be engaged by pawls c c and rotated thereby in the reciprocating movement of the feed-shat t a. The cutter-ratchet 0 1's rotated in an opposite direction from the ratchet c, a cam projection c in the rotation of the ratchet engaging ashoulder e on the main rock-shaft e. A pliigger-arm 0 extends from the rock-shaft e, to which is pivoted a rod 6, the opposite end-of the rod being pivoted to an arm f, secured to a plugger rock-shaft f. This rockshaft is suitably mounted in a standard supported on the table, the opposite end of this rock-shaft supporting an arm f to the lower end of which is pivoted a plugger-wheel f. This arm f is preferably made in two sections, adjustably connected.

A plugger-guideg is supported on the table, through which extend pluggers 71. and guiderods 72 these pluggers and guide-rods being secured to the plugger-support h. A shoulder 'h is formed on the plugger-support, against which the plugger-wheel f strikes in the swinging movement of the arm A spring it causes one of the arms on the wheel to lie in normal position to surely engage the shoulder ]L3. The pluggers h are made of a length to lie in close proximity to the table a when the pluggersupport is at the lower limit of its play and for the purpose of clamping a card between the pluggers and the table, the pluggers being suitably spaced to overliea needle-hole made in the operation of sewing the hooks and eyes to the card.

A cutter-arm t'is secured to the main rockshaft e, the opposite end of the cutter-arm having secured thereto a cutter 7t, that projects across underneath the table in a position to underlie the cards on which the hooks and eyes are being secured, a spring 76 holding the cutter normally at the rearward limit of its play and against a cutter-stop k adjustably mounted in'the cutter-stop support The forward end of the cutter projects into a cutter-box Z, and a cutter-cam m is pivoted to the cutter in a position to liein the cutterboX. Acam-shoulder is formed in the slot Z in the cutter-box, this shoulder being pref erably formed of a separate piece lying within the slot and adj ustably secured to the box. A spring 7& is employed for holding the cutter normally at the lower limit of its play.

The cutter-box Z is adjustably mounted in a bracket Z secured to the table. The means for moving the box on the bracket and for adjustably securing the box to the bracket and holding it adjustably thereon may be of any form desired. In the form herein shown the box Z has a projection of dovetail shape fitting a groove of the same shape in the bracket Z (see Fig. 4,) and a set-screw (not shown) may be employed for holding the box in position.

The operation of the device is as follows: The hooks and eyes having been placed in position on the holders and a card inserted underneath the holder, the rack of the holder is engaged with a feed-pinion b to an extent tate the ratchet-feed c in a step-by-step movement, which operation feeds the card underneath the needle. This operation of the rockshai't also causes the cutter-ratchet to be rotated in a step-by-step movement by means of the cutting-pawl 0 This step-by-step movement is so timed that the projection 0 will engage the shoulder e on the main rockshaft at about the time the needles are sewing the last hook and eye to the card, and in any event at such time as to cause the main shaft to be rocked to cause the thread to be severed just after the last hook and eye has been secured to the card. The movement of the main rock-shaft e causes the operation of the plugger rock-shaft, swinging the arm f and causing the plu'gger-wheel to engage the shoulder h on the plugger-support, forcing the latter downward and causing the pluggers h to press the card against the table, each of the pluggers coming in contact with a hole formed by a needle and forcing the material into the hole and closing the same to prevent the thread from pulling out. In this operation the plugger-support is forced gradually downward, the pluggers being held in contact with. the card, however, but for an instant,,and as one of the arms on the wheel passes the center the force of the springs on the pluggers carries the plugger support quickly upward, which movement is permitted by the free rotation of the wheel on its pivot. The movement of the main rockshaft 6 also swings the cutter-arm i, causing the cutter is to be moved forward, in which operation the cutter-cam on, coming in contact with the cam-shoulder Z in the cutterbox, forces the cutter upward against the tension of the spring 1%. This cutter-cam is so formed that the cutter makes engagement with the card to an extent to sever the thread, 5 the several parts being so timed that the pluggers press the card to the table just before the cutter operates to sever the thread, this pressing of the pluggers on the card holding the thread tightly and preventing its pulling through the holes under the pressure of the cutter. As a point on the cutter-cam passes a central line through said point and the pivot the cutter is drawn quickly downward under the force of the spring 70 This quick movement of the cutter and of the pluggers away from the cards is for the purpose of allowing the free forward movement of the cards from the machine under its continued operation. The cutter is drawn 2o quickly backward under the force of the spring is until it rests with the arm 1' in contact with the stop 75*. The next card is fed into the machine until the required number of books and eyes are secured thereto, when the operation of the plugger and cutter is repeated.
